Answer:
k = -4
Step-by-step explanation:
(k - 10)/2 = -7
First: multiply by 2 to get rid of the denominator
2(k - 10)/2 = 2(-7)
k - 10 = -14
Next: add 10 to both sides to isolate k
k - 10 + 10 = -14 + 10
k = -4
this equation ( /2x-1/=5)can be solved if we solve the following equations:
2x-1=5
2x-1=-5
1)We solve the first equation:
2x-1=5
2x=5+1
2x=6
x=6/2
x=2
2) we solve the second equation.
2x-1=-5
2x=-5+1
2x=4
x=-4/2
x=-2
The solutions of this equation /2x-1/=5 will be: x=3 and x=-2
Answer: x=3 and x=-2
